Am working on odoo community version 11 in windows, I have been asked to customize a report for POS sale details which is present in Point of Sale, the report contains only two fields quanity and price, therefore I need to add more fields but am not that much experienced in programming from back end, but am familiar with customization from the front end..
I would be helpful if someone tell me how to make changes in the existing Pos sale detail report from the xml view or any other source.
